How the Zid merchant app became an acquisition channel: in-app registration, onboarding and a PLG strategy that held up when the business model changed mid-project.
Zid's merchant app was being downloaded at a high rate, but new users couldn't register or create a store inside it. Every download from someone new was a dead end.
The question wasn't just "how do we add sign-up to mobile". It was two harder ones:
I approached it end to end, from the moment someone downloads the app to the moment their store is live and subscribed, so registration, store creation and onboarding worked as one journey.

I led UX for the Zid app: a full audit of the app, then redesigns of the experiences that decide whether a merchant succeeds.
I combined Clarity heatmaps and funnel data, past surveys, personas and interviews, an audit of the web registration, and competitive benchmarks. Four findings shaped the design:



Close to release, Zid removed its free plan. New merchants could register in the app, but couldn't subscribe there. Three options were on the table:
High download numbers meant real interest. Removing the free plan didn't remove the value. It changed where we showed it.
